	   $self->emit(roar => 3);
	 }

	 package main;

	 # Subscribe to events

	 $tiger->on(roar => sub {
	   my ($tiger, $times) = @_;
	   say 'RAWR!' for 1 .. $times;
	 });
	 $tiger->poke;

DESCRIPTION

       Mojo::EventEmitter is a simple base class for event emitting objects.

METHODS

       Mojo::EventEmitter inherits all methods from Mojo::Base and implements the following new ones.

   "emit"
	 $e = $e->emit('foo');
	 $e = $e->emit('foo', 123);

       Emit event.

   "emit_safe"
	 $e = $e->emit_safe('foo');
	 $e = $e->emit_safe('foo', 123);

       Emit event safely and emit "error" event on failure.

   "has_subscribers"
	 my $success = $e->has_subscribers('foo');

       Check if event has subscribers.

   "on"
	 my $cb = $e->on(foo => sub {...});

       Subscribe to event.

	 $e->on(foo => sub {
	   my ($e, @args) = @_;
	   ...
	 });

   "once"
	 my $cb = $e->once(foo => sub {...});

       Subscribe to event and unsubscribe again after it has been emitted once.

	 $e->once(foo => sub {
	   my ($e, @args) = @_;
	   ...
	 });

   "subscribers"
	 my $subscribers = $e->subscribers('foo');

       All subscribers for event.

	 # Unsubscribe last subscriber
	 $e->unsubscribe(foo => $e->subscribers('foo')->[-1]);

   "unsubscribe"
	 $e = $e->unsubscribe('foo');
	 $e = $e->unsubscribe(foo => $cb);

       Unsubscribe from event.
